The siegen 9 piece extra long metric ball end hex key set is a professional grade toolkit designed for accessing hard to reach fixings in automotive, mechanical and engineering applications. Manufactured from heat treated and hardened chrome vanadium steel with a blackened finish, this comprehensive set delivers exceptional durability and corrosion resistance for demanding workshop environments. The extra long design extends from 90mm to 230mm, providing superior reach into recessed areas where standard hex keys cannot access. Each key features a ball end design that allows you to drive fixings at angles up to 30°, particularly useful when working in confined spaces or around obstructions where perpendicular access is restricted. The set covers the most commonly used metric sizes from 1.5mm through to 10mm, making it suitable for a wide range of mechanical tasks including bicycle maintenance, furniture assembly, machinery servicing and vehicle repairs. Keys are supplied in an easy access storage case with a hanging tag for organised workshop storage and quick size identification.
